Multiple Falls in the Elderly

Clinical Scenario

A district nurse calls about Margaret Foster, 78, who has had two falls at home in the past 5-6 weeks. Both were mechanical falls on standing, without injury on the most recent occasion but with a previous arm laceration. Margaret lives alone, is becoming frailer, has lost weight, and her confidence has dropped significantly. She is on 8 medications including ramipril, bendroflumethiazide, citalopram, and amitriptyline. Her lying-standing blood pressure shows a small drop (122/70 to 120/68). Her gait is unsteady. Her daughter visits twice weekly.

What This Case Tests

Conducting a comprehensive multifactorial falls assessment; identifying medication-related falls risk (multiple hypotensives, SSRIs, tricyclics); assessing for postural hypotension, frailty, and malnutrition; coordinating a community falls prevention response; balancing investigation with practical intervention.

Common Mistakes Trainees Make

The three most common mistakes are: treating the falls as simple mechanical events without conducting a multifactorial assessment (recurrent falls in the elderly are rarely single-cause), not reviewing the medication list for falls-contributing drugs (Margaret is on two antihypertensives, an SSRI, and a tricyclic — all increase falls risk), and ordering extensive investigations without addressing the immediately modifiable risk factors (home hazards, medication rationalisation, nutrition, strength and balance).

The Consultation Challenge

Recurrent falls in a 78-year-old living alone are a clinical and safeguarding priority. The falls are almost certainly multifactorial, and the consultation tests whether you can systematically identify and address the contributing factors rather than attributing them to "getting older."

Start with the falls history through the district nurse. For each fall: what was she doing, time of day, any warning symptoms (dizziness, palpitations, visual disturbance), any loss of consciousness, how did she get up, and any injuries. Mechanical falls on standing without prodromal symptoms or loss of consciousness suggest postural instability rather than cardiac or neurological cause — but you must screen for both.

Conduct a systematic multifactorial assessment. The key domains are:

Medications: Margaret is on ramipril and bendroflumethiazide (both lower blood pressure), citalopram (SSRIs increase falls risk by 60-70% in the elderly), amitriptyline (tricyclic — sedation, anticholinergic effects, postural hypotension), and lansoprazole (hyponatraemia risk with SSRIs). This medication combination is high-risk for falls.

Cardiovascular: lying-standing BP shows only a small drop currently, but this may fluctuate. Check for arrhythmias (AF, bradycardia), consider 24-hour BP monitoring if suspicion of symptomatic hypotension.

Nutrition and frailty: weight loss and reduced mobility suggest frailty. Assess nutritional intake, screen for sarcopenia, and consider vitamin D deficiency (extremely common in housebound elderly — contributes to muscle weakness and falls).

Home environment: rugs, dim lighting, no grab rails, clutter — these are modifiable risk factors that an occupational therapy assessment can address.

Strength and balance: refer to community falls prevention service for a structured exercise programme — evidence shows this reduces falls by 30-40%.

Arrange bloods: FBC (anaemia), U&Es (sodium — SSRIs and PPIs both cause hyponatraemia), HbA1c (diabetes control), TFTs, calcium, vitamin D, and bone profile. Consider a DEXA scan given the falls and age.

Time check: Spend the first 4 minutes on the falls history and current clinical picture. By minute 7, conduct the systematic multifactorial assessment. Use minutes 8-10 for the management plan (medication review, investigations, referrals). Reserve the final 2 minutes for home safety planning and follow-up.

How Examiners Mark This Case

Data Gathering and Diagnosis: Examiners assess whether you take a detailed falls history for each event, screen for cardiac causes (syncope, arrhythmia), neurological causes (stroke, Parkinson's), and medication-related causes. They look for a systematic multifactorial assessment covering medications, cardiovascular status, nutrition, bone health, vision, home environment, and gait and balance. A trainee who investigates one domain in depth but misses others will score poorly.

Clinical Management and Medical Complexity: Examiners expect medication review as a priority (identifying the high-risk combination), appropriate investigations (bloods including sodium and vitamin D), referral to community falls service for strength and balance, occupational therapy for home assessment, and consideration of bone protection. Demonstrating the stepped approach — address modifiable factors before ordering extensive tests — shows clinical pragmatism.

Relating to Others: Examiners assess whether you communicate effectively through the district nurse (using her as a clinical partner), address Margaret's loss of confidence (which can accelerate decline through fear-avoidance), and involve the daughter in the safety planning. The management should feel proactive and empowering, not just reactive to the falls.

Example Opening

Strong opening: "Thank you for calling — two falls in six weeks is definitely something we need to take seriously. Can you walk me through each fall? I need to know exactly what happened, what time of day, and whether Margaret had any warning signs beforehand."

When addressing medications: "Looking at Margaret's medication list, I think several of her tablets may be contributing to the falls. She's on two blood pressure medications, an antidepressant, and amitriptyline — all of which can affect balance and blood pressure on standing. I'd like to review these and see what we can safely reduce or stop."

Avoid: "Falls are quite common at her age." (Normalises a preventable and potentially dangerous condition).

How This Appears in the SCA

Recurrent falls is a bread-and-butter elderly care SCA topic. Examiners assess whether you take a structured multifactorial approach rather than a single-cause approach, identify medication-related risk, and coordinate a community prevention response. The medication review element overlaps with polypharmacy management skills.

Key Statistic

Falls affect approximately 30% of people over 65 annually, rising to 50% over 80. Recurrent falls are the leading cause of injury-related death in the over-75s. A structured multifactorial assessment and intervention programme reduces falls by 20-30%. Medication review alone can reduce falls by 10-15%.

Frequently Asked Questions

What is a multifactorial falls assessment?

NICE CG161 recommends assessing: falls history and circumstances, medication review (especially psychotropics, antihypertensives, and polypharmacy), cardiovascular assessment (postural hypotension, arrhythmia), gait, balance and mobility, osteoporosis risk, vision, cognitive function, continence, home environment hazards, and fear of falling. Addressing multiple factors simultaneously is more effective than targeting any single cause.

Which medications increase falls risk in the elderly?

The highest-risk medications include: SSRIs (60-70% increased falls risk), benzodiazepines, tricyclic antidepressants (amitriptyline), opioids, antihypertensives (particularly when multiple agents are combined), anticholinergics, and antipsychotics. In Margaret's case, citalopram plus amitriptyline plus two antihypertensives creates a significant cumulative risk. Medication review is one of the most effective single interventions for falls prevention.

How effective are falls prevention programmes?

Structured strength and balance exercise programmes (such as Otago or FaME) reduce falls by 30-40% in community-dwelling older adults. Multifactorial interventions (exercise plus medication review plus home assessment plus vision correction) reduce falls by 20-30%. These are evidence-based, cost-effective interventions available through community falls prevention services. Referral demonstrates strong Clinical Management.

Should I check vitamin D in an elderly patient who is falling?

Yes — vitamin D deficiency is present in approximately 50% of housebound elderly patients and contributes to muscle weakness, poor balance, and increased falls risk. NICE recommends vitamin D supplementation (800 IU daily) for all adults over 65, and replacement therapy if deficiency is confirmed. Checking the level and supplementing is a simple, evidence-based intervention that is frequently overlooked.

When should recurrent falls in the elderly trigger a safeguarding concern?

Consider safeguarding if: the falls are occurring in a context of self-neglect (poor nutrition, inadequate heating, hoarding), there are concerns about carer-related harm, the patient is unable to summon help after a fall and lives alone, or there are unexplained injuries inconsistent with the reported mechanism. Margaret living alone with weight loss and increasing frailty warrants a holistic assessment that includes safeguarding considerations.
